Description

Technical Field

[0001] The present invention relates to the technical field of intelligent environmental regulation, and particularly to an intelligent environmental regulation method and system for free-range chicken breeding. Background Art

[0002] Free-range chickens are a type of poultry, different from caged broiler chickens. They refer to chickens raised in mountain forests and orchards. Free-range chickens have characteristics such as being able to tolerate roughage, having a strong brooding instinct, and strong disease resistance. Moreover, the meat of free-range chickens is delicious, the eggs have excellent quality, and are rich in nutrition, containing abundant protein, amino acids, and gelatin protein, and also containing more trace elements and various nutrients, with a relatively low fat content, so they are more favored by consumers. During the breeding process of free-range chickens, the breeding of young free-range chickens is crucial. The digestive function of young free-range chickens is not complete, and their ability to regulate body temperature is poor, so they need to be carefully raised. And the growing free-range chickens are an important stage in the growth of free-range chickens, which is related to the yield and quality of free-range chickens.

[0003] Currently, the scale of free-range chicken breeding in rural areas is small and not concentrated. Most farmers have not received professional training, resulting in unscientific breeding methods, low yields, high prices but low profit margins. Therefore, there is an urgent need for an intelligent environmental regulation method for free-range chicken breeding to enable farmers to breed scientifically and reasonably. On the one hand, it can increase the income of farmers. On the other hand, it can provide free-range chickens in the market with reasonable prices, tender meat, delicious taste, high quality and meeting the requirements of green food, which are green and healthy, but have a long breeding time and low survival rate, making it difficult to meet people's demand for chickens.

For those of ordinary skill in the art, without creative efforts, other drawings can also be obtained based on these drawings.

[0036] Figure 1 It is a flowchart of an intelligent control method for the breeding environment of native chickens according to an embodiment of the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0038] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0039] This embodiment discloses the acquisition methods of various parameters:

[0040] Method for obtaining environmental parameter values:

[0041] 1. Measurement of temperature, humidity, light, and air quality:

[0042] Temperature and humidity: It can be measured by using a DHT11 sensor. The DHT11 is a commonly used temperature and humidity sensor that can provide measurements of relative humidity and temperature. In an embedded system, the data of the DHT11 sensor can be read by writing the corresponding driver program. For example, on the STM32 platform, the pins can be defined and the ADC channels can be initialized, and then the sensor data can be read through I2C communication.

[0043] Light: The light intensity can be measured by a photosensitive sensor, and the output of this sensor can be connected to the ADC (Analog / Digital Converter) channel of the microcontroller. By reading the ADC value, it can be converted into the value of light intensity.

[0044] Air quality: The air quality can be measured by specific air quality sensors, which can detect pollutants in the air, such as PM2.5, PM10, VOCs, etc. The output of the sensor can also be connected to the ADC channel of the microcontroller, and the air quality index can be obtained by reading the ADC value.

[0045] 2. Data reading and processing:

[0046] Reading the ADC value: Configure the ADC channel by writing a function, start the ADC conversion, and read the conversion result. For example, on the STM32 platform, the ADC channel can be configured, the conversion can be started, and the conversion completion can be waited for through polling, and finally the ADC value can be read.

[0047] Data processing: The raw ADC value read needs to be converted into the actual physical quantity value. This usually involves the conversion of the reference voltage and the ADC resolution.

[0048] Method for obtaining growth performance:

[0049] 1. Measurement of growth rate, body weight change, and feed conversion ratio:

[0050] Growth rate and body weight change: The growth rate and body weight change can be monitored by regularly weighing the animals. These data can be recorded manually or collected using an automated weighing system.

[0051] Feed conversion ratio: The feed conversion ratio (FCR) refers to the ratio of the amount of feed consumed by an animal to its weight gain. This can be calculated by recording the feed consumption and weight gain within a certain period of time.

[0052] 2. Data recording and analysis:

[0053] Data recording: Data on growth performance need to be recorded regularly, which can be done manually or using an automated data recording system.

[0054] Data analysis: The collected data can be evaluated for growth performance through statistical analysis methods, such as calculating the Average Daily Gain (ADG) and feed conversion ratio.

[0055] Methods for obtaining immune levels:

[0056] 1. Blood sample analysis:

[0057] Measurement of immune indicators: Immune levels can be evaluated by analyzing immune indicators in blood samples. This includes immunoglobulins such as IgA, IgG, IgM, and cytokines such as IL-6.

[0058] Blood sample collection: Blood samples can be obtained by methods such as venipuncture or cardiac puncture. After collection, the samples need to be properly processed, such as centrifuging to separate the serum.

[0059] 2. Determination of immune indicators:

[0060] Determination of immunoglobulins: Immunoglobulins can be determined by enzyme-linked immunosorbent assay (ELISA). This is a commonly used laboratory technique that can quantitatively analyze specific proteins in serum.

[0061] Determination of cytokines: Cytokines such as IL-6 can be determined by flow cytometry or multiplex cytokine detection techniques, which can simultaneously detect the levels of multiple cytokines.

[0062] Through the above methods, relevant parameters of environmental parameters, growth performance, and immune levels can be systematically obtained, providing data support for further analysis and application. The implementation of these methods requires combination with specific experimental conditions and equipment to ensure the accuracy and reliability of the data.

[0063] As Figure 1 shown, this embodiment discloses an intelligent control method for the breeding environment of native chickens, which is characterized by including: obtaining the heat demand and current temperature during the brooding period of native chickens, determining the target temperature during the brooding period of native chickens according to the heat demand, adjusting the current temperature until the target temperature is reached; obtaining the environmental parameter values, growth performance, and immune levels at different historical moments during the growth period of native chickens, determining the change relationship between the environmental parameter values and growth performance, immune levels during the growth period of native chickens according to the environmental parameter values, growth performance, and immune levels, and obtaining the optimal environmental parameter values at different moments during the growth period of native chickens based on the change relationship; obtaining the current environmental parameter values during the growth period of native chickens, and adjusting the current environmental parameter values during the growth period of native chickens until the optimal environmental parameter values are reached.

[0064] Further, adjusting the current temperature until the target temperature is reached includes: determining whether the current temperature is the same as the target temperature. If the current temperature is the same as the target temperature, there is no need to adjust the power of the heating device. If the current temperature is not the same as the target temperature, the power of the heating device is dynamically adjusted until the target temperature is reached.

[0065] Specifically, obtain the temperature change rate of the heating device during the brooding period of the native chickens; control the operation of the temperature control unit according to the target temperature change rate; determine whether the current temperature is the same as the target temperature. If the current temperature is the same as the target temperature, there is no need to adjust the power of the heating device. If the current temperature is not the same as the target temperature, the power of the heating device is dynamically adjusted until the target temperature is reached.

[0066] Further, adjusting the current temperature until the target temperature is reached also includes: while adjusting the current temperature, continuously performing operations such as egg turning, egg cooling, and egg candling on the native chickens during the brooding period until hatching.

[0067] Specifically, clean the native chicken eggs during the brooding period with water at 30 - 40 °C and send them to the hatching room within 30 minutes; control the temperature during the hatching process between 35 - 38 °C and the humidity between 45 - 70%, and continuously perform operations such as egg turning, egg cooling, and egg candling until hatching; transfer the hatched chicks to the brooding box 1 - 2 hours after hatching, and control the environmental temperature during the brooding process above 20 °C.

[0068] Further, the environmental parameter values include: temperature, humidity, light, and air quality; the growth performance includes: growth rate, weight change, and feed conversion rate; the immune level includes: analyzing the immune indicators in the serum of the blood sample, such as IgA, IgG, IgM, IL - 6, etc.

[0069] Further, determining the change relationship between the environmental parameter values and the growth performance and immune level during the growth period of the native chickens includes: according to the environmental parameter values, growth performance, and immune level at different historical moments during the growth period of the native chickens, determine the effective influence duration of the environmental variables during the growth period of the native chickens on the growth performance and immune level during the growth period of the native chickens; obtain the environmental parameter values and the corresponding historical moments within the effective influence duration, use the environmental parameter values corresponding to the growth performance and immune level within the effective influence duration as the output layer, use the environmental parameter values and the corresponding historical moments within the effective influence duration as the input layer, train and converge the neural network model, and obtain the prediction model of the growth state of the native chickens corresponding to the growth performance and immune level; according to the prediction model of the growth state of the native chickens, determine the change relationship between the environmental parameter values and the growth performance and immune level during the growth period of the native chickens.

[0070] Specifically, in this embodiment, it is necessary to figure out how environmental factors affect the growth and immunity of native chickens during their growth process. Specifically, in this embodiment, it is first necessary to find out which environmental factors have an impact on their growth and immunity at different stages of the growth of native chickens, and how long this impact can last. Then, this embodiment will select environmental parameters and corresponding growth and immunity data during this period, and use these data to train a neural network model until the model can accurately predict the growth state of native chickens. Finally, this embodiment can use this model to determine how environmental factors affect the growth and immunity of native chickens over time.

[0071] Further, obtaining the effective influence duration includes: obtaining several peaks of the environmental parameter values and the corresponding historical moments within the historical period according to the environmental parameter values at different historical moments during the growth period of native chickens, and determining the duration of each adjacent peak interval period of the environmental parameter values within the historical period; obtaining several peaks of the growth performance and immunity level and the corresponding historical moments within the historical period based on the growth performance and immunity level at different historical moments during the growth period of native chickens, and determining the duration of each adjacent peak interval period of the growth performance and immunity level within the historical period; performing time period duration feature matching and time period duration sequence feature matching on the duration of each adjacent peak interval period of the environmental parameter values within the historical period and the duration of each adjacent peak interval period of the growth performance and immunity level within the historical period, and obtaining the lag duration between the change of the environmental parameter values and the change of the growth performance and immunity level during the growth period of native chickens as the effective influence duration.

[0072] Specifically, first, it is necessary to find out the highest values, that is, their "peaks", of the environmental parameters, growth performance, and immunity level at different time points during the growth of native chickens, as well as the specific time when these peaks appear. Then, it is necessary to calculate the time intervals between these peaks, that is, how long it takes from one peak to the next. Specifically, this embodiment needs to first look at the highest values of the environmental parameters at different time points and the time when they appear, and then calculate the time intervals between these highest values. The same method is also used for the growth performance and immunity level of native chickens to find their highest values and times, as well as the time intervals between these highest values. Next, it is necessary to compare these time intervals to see if there is a time delay between the change of the environmental parameters and the change of the growth performance and immunity level of native chickens. That is to say, whether the change of the environmental parameters occurs before or after the growth and immune responses of native chickens. By comparing these time intervals, the effective duration of the impact of environmental parameter changes on the growth and immunity of native chickens can be determined, that is, the time range of the impact of environmental changes on native chickens.

[0073] Further, the method further includes: visually displaying the current temperature during the brooding period of native chickens and the current environmental parameter values during the growth period of native chickens.

[0074] This embodiment also discloses an intelligent control system for the breeding environment of native chickens, including: a brooding period environment control module, which is used to obtain the heat demand and current temperature during the brooding period of native chickens, determine the target temperature during the brooding period of native chickens according to the heat demand, and adjust the current temperature until the target temperature is reached; an optimal environment parameter acquisition module, which is used to obtain the environmental parameter values, growth performance and immune level at different historical moments during the growth period of native chickens, determine the change relationship between the environmental parameter values and the growth performance and immune level during the growth period of native chickens according to the environmental parameter values, growth performance and immune level, and obtain the optimal environmental parameter values at different moments during the growth period of native chickens based on the change relationship; a growth period environment control module, which is used to obtain the current environmental parameter values during the growth period of native chickens and adjust the current environmental parameter values during the growth period of native chickens until the optimal environmental parameter values are reached.

[0075] Furthermore, the system also includes: a visualization display module, which is used to visually display the current temperature during the brooding period of native chickens and the current environmental parameter values during the growth period of native chickens.

[0076] The above-described embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
